型钢混凝土柱的非线性有限元分析

型钢混凝土柱在现代建筑中越来越多的被采用,以解决普通钢筋混凝土柱在高轴压比下抗震不利的状况。文章基于通用非线性有限元软件ABAQUS对型钢混凝土柱进行水平荷载作用下单调加载全过程模拟,研究了对于型钢混凝土结构的单元选择,材料本构关系的选取。计算结果表明,型钢混凝土柱具有较高的承载能力,较大刚度,骨架曲线下降段较为平缓,具有较好的延性和较好的耗能能力。

Non-linear Finite Element Analysis of Steel Reinforced Concrete Column

Steel reinforced concrete column are more and more used in modem architecture, in order to solve the unfavorable anti-seismic situation of ordinary reinforced concrete column under high axial compression ratio. Based on the general nonlinear finite element software ABAQUS for steel reinforced concrete columns under the action of horizontal loading monotonic loading process simulation, it studied the unit for steel reinforced concrete structure selection, material selection of constitutive relations. The results show that the steel reinforced concrete column with high bearing capacity, large stiffness, skeleton curves decline period of relatively flat, has good ductility and good energy dissipation capacity.
